To @ZZ whom, it may concern:

Be it known that I, LUTHER F. LooKE, a citizen of the United States,residing at Nashua, in the county of Hillsborough and State of NewHampshire, have invented certain new and usefullmprovements inVentilated Shoes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to ventilated shoes; and it consists in a shoeconstructed with an air-induction passage leading down from the top ofthe rear or side portion of the upper leather into an air-well beneaththe insole or lining of the heel portion of the shoe, said air-wellbeing covered with a spring air-forcing diaphragm operated by the heelof the foot, and said air-well also being combined with an induction andeduction valve and with alongitudinal T-shapedv air-channel-way andperforations in the insole of the shoe, in communication with thetransverse portion of the channel-way, all as will be hereinafterdescribed, whereby air is introduced into the shoe and discharged intothe chamber of the shoe in contact with the foot, it passing up betweenthe toes thereof and allowed to find its way out of the shoe between thefoot and the upper leather, escaping at the top of the shoe above theankle.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection of a shoe constructed in accordance with my invention. Fig. 2 isa horizontal section of the same on a line above the insole. Fig. 3 is across-section of a portion of the shoe in the line of theventilating-passages. Fig. is an enlarged broken longitudinal section ofthe heel portion of the shoe, and Fig. 5 shows the invention in anotherform.

A in the accompanying drawings designates the sole of the shoe, B theheel, and O the upper leather thereof.

D is an air-well formed in the upper side of the heel of the shoe.

E is an induction air-passage arranged, preferably, near theankle-joint, as in Fig. 5, and provided with a valve a, in communicationwith said air-well, and D is an eduction air-channel-way provided with avalve b, also in communication with the air-well. The

Vchamber of the shoe.

air-channel-way D runs along the center of the outer sole on the upperside thereof, and at its forward end is extended laterally, preferablyon an oblique line, as in Fig. 5, in opposite directions to near sideedges of said sole, and in this laterally-extended portion the aircirculates and passes up between the toes of the wearer of the shoe. Theair-well and the air-channel-way are covered by the inner sole c, andthrough this inner sole, directly over the laterally-extendedchannelway, numerous Ventilating-holes c are formed for the escape ofair between the toes into the To the under side of the insole aspring-diaphragm F, of the form shown by dotted lines in Fig. 2 and insection in Fig. 1, is applied. That portion of this diaphragm which isdirectly over the air-well is left free to be depressed into theair-well, as illustrated by the dott-ed lines in Fig. 1, and itsdownward movement is limited by means of a shoulder c, formed in theside of the wall of the well. The induction air-passage E is shown inFigs. 1, 2, and 4 formed in the rear or heel portion of the upper andits valve a arranged to open inward or forward to the entrance of theair and close backward against the escape of air, while in Fig. 5 saidpassage is located near the ankle-joint. The eductionvalve b opensforward to the escape of the air from the air-well into the Ventilatingchannel-way D and closes backward against the escape of the air fromsaid channel-way.

The operation is afollows: The air [ills the air-well and is trapped.The person wearing the shoe, by depressing the diaphragm with his heel,forces the air out of the air-well into the channel-way and through theVentilatingpassages into the shoe at points between the toes of thefoot, the return of the air` being prevented by the valve b closing theentrance from the channel-way to the air-Well. The foot is thus cooledand the shoe ventilated, and as fast as the air becomes warmedcirculates out of the shoe between the foot and the upper-leather, itsdischarge being above the ankle or at such point as there may be anoutlet from the shoe.

What I claim as my invention is- The ventilated shoe provided with anairentrance passage, an air-well in the body of the heel, alimitation-shoulder on one of the IOO walls of the air-well and belowthe inner upto pass between the toes of the wearer and per surface ofthe heel, perforated insole, an around the upper part of the foot andout at air-ohannel-way having lateral branches in the usual opening ofthe shoe through which communication with and leading from it and thefoot is inserted, all substantially as de- 15 5 extending beneath theperforations in the inscribed.
